SERVSWITCH™ WIZARD MP
A.3 Cabling Attached to the OPTIONS/FLASH Port
The DB15 connector labeled “OPTIONS/FLASH” on the back of the ServSwitch
Wizard MP is a proprietarily pinned port using RS-232-type signaling. You can
connect either of these devices to it:
• The Wizard MP’s optional Remote-Control Module (RCM, see
Section 5.2
);
• A PC, in order to upgrade the Wizard MP’s firmware (see
Section 5.12
).
The pinout of this connector is pretty simple: Pin 9 (Signal Ground, SGND),
Pin 10 (Transmit Data, TD), and Pin 11 (Receive Data, RD) are the only pins used
for serial communication to PCs. All other pins are intended for RCM
communication only and should be left unconnected; attaching them to PCs could
have unpredictable and possibly damaging effects.
The pinout for the Wizard MP’s included firmware-upgrade cable is shown in
Figure A-2. If you ever need to replace this cable, you can order it separately as
product code KV6SER.
